During Stocks experiments he found that a smooth copper saw, in the form of a 6mm wide slab (to match found tool marks), worked best with dry sand as
grit for cutting granite. Serrated blades proved less effective. All it took was time and labor.

Was that the "Woodwrights Shop"? great show, although it's star (Roy Underhill) was a bit of a stumblebum.

That sounds about right, though it was some time ago, but it showed what could be done without electric tools, or at least I don’t remember any used
on the show. It was wood that was crafted on the show, but I could see how some techniques could easily be translated to other materials as well.
